they are for next wednesdays performance.i might as well have them, i said sadly.lesson20 one man in a boat 独坐孤舟fishing is my favourite sport. i often fish for hours without catching anything. but this does not worry me. some fishermen are unlucky. instead of catching fish, they catch old boots and rubbish. i am even less lucky. i never catch anything-not even old boots. after having spent whole mornings on the river, i always go home with an empty bag. you must give up fishing! my friends say. its a waste of time. but they dont realize one important thing. im not really interested in fishing. i am only interested in sitting in a boat and doing nothing at all !lesson21 mad or not? 是不是疯了?aeroplanes are slowly driving me mad. i live near an airport and passing planes can be heard night and day. the airport was built during the war, but for some reason it could not be used then. last year, however, it came into use. over a hundred people must have been driven away from their homes by the noise. i am one of the few people left. sometimes i think this house will be knocked down by a passing plane. i have been offered a large sum of money to go away, but i am determined to stay here. everybody says i must be mad and they are probably right.lesson22 a glass envelope 玻璃信封my daughter, jane, never dreamed of receiving a letter from a girl of her own age in holland. last year, we were travelling across the channel and jane put a piece of paper with her name and address on it into a bottle. she threw the bottle into the sea. she never thought of it again, but ten months later, she received a letter from a girl in holland. both girls write to each other regularly now. however, they have decided to use the post-office. letters will cost a litt1e more, but they will certainly travel faster. lesson23 a new house 新居i had a letter from my sister yesterday. she lives in nigeria. in her letter, she said that she would come to england next year. if she comes, she will get a surprise. we are now living in a beautiful new house in the country. work on it had begun before my sister left. the house was completed five months ago. in my letter, i told her that she could stay with us. the house has many large rooms and there is a lovely garden. it is a very modern house, so it looks strange to some people. it must be the only modern house in the district.lesson24 it could be worse 不幸中之万幸i entered the hotel managers office and sat down. i had just lost &50 and i felt very upset. i left the money in my room, i said, and its not there now. the manager was sympathetic, but he could do nothing. everyones losing money these days, he said. he started to complain about this wicked world but was interrupted by a knock at the door. a girl came in and put an envelope on his desk. it contained &5o. i found this outside this gentlemans room she said. well, i said to the manager, there is still some honesty in this world !lesson25 do the english speak english? 英国人讲的是英语吗?i arrived in london at last. the railway station was big, black and dark. i did not know the way to my hotel, so i asked a porter. i not only spoke english very carefully, but very clearly as well. the porter, however, could not understand me; i repeated my question several times and at last he understood. he answered me, but he spoke neither slowly nor clearly. i am a foreigner, i said. then he spoke slowly, but i could not understand him. my teacher never spoke english like that! the porter and i looked at each other and smiled. then he said something and i understood it. youll soon learn english! he said. i wonder. in england, each man speaks a different language. the english understand each other, but i dont understand them ! do they speak english ?lesson26 the best art critics 最佳美术评论家i am an art student and i paint a lot of pictures. many people pretend that they understand modern art. they always tell you what a picture is about. of course, many pictures arc not about anything. they are just pretty patterns. we like them in the same way that we like pretty curtain material. i think that young children often appreciate modern pictures better than anyone else. they notice more. my sister is only seven, but she always tells me whether my pictures are good or not. she came into my room yesterday. what are you doing ? she asked. im hanging this picture on the wall, i answered. its a new one. do you like it ? she looked at it critically for a moment. its all right, she said, but isnt it upside-down ? i looked at it again. she was right! it was!lesson27 a wet night 雨夜late in the afternoon, the boys put up their tent in the middle of a field. as soon as this was done, they cooked a meal over an open fire. they were all hungry and the food smelt good. after a wonderful meal, they told stories and sang songs by the camp fire. but some time later it began to rain. the boys felt tired so they pet out the fire and crept into their tent. their sleeping-bags were warm and comfortable, so they all slept soundly. in the middle of the night, two boys woke up and began shouting. the tent was full of water! they all leapt out of their sleeping-bags and hurried outside. it was raining heavily and they found that a stream had formed in the field. the stream wound its way across the field and then flowed right under their tent!lesson28 no parking 禁止停车jasper white is one of those rare people who believes in ancient myths. he has just bought a new house in the city, but ever since he moved in, he has had trouble with motorists. when he returns home at night, he always finds that someone has parked a car outside his gate. because of this, he has not been able to get his own car into his garage even once. jasper has put up no parking signs outside his gate, but these have not had any effect. now he has put an ugly stone head over the gate. it is one of the ugliest faces i have ever seen. i asked him what it was and he told me that it was medusa, the gorgon. jasper hopes that she will turn motorists to stone. but none of them has been turned to stone yet!lesson29 taxi! 出租汽车!captain ben fawcett has bought an unusual taxi and has begun a new service. the taxi is a small swiss aeroplane called a pilatus porter. this wonderful plane can carry seven passengers. the most surprising thing about it, however, is that it can land anywhere: on snow, water, or even on a ploughed field. captain fawcetts first passenger was a doctor who flew from birmingham to a lonely village in the welsh mountains. since then, captain fawcett has flown passengers to many unusual places. once he landed on the roof of a block of flats and on another occasion, he landed in a deserted car park. captain fawcett has just refused a strange request from a businessman. the man wanted to fly to rockall, a lonely island in the atlantic ocean, but captain fawcett did not take him because the trip was too dangerous.lesson30 football or polo? 足球还是水球?the wayle is a small river that cuts across the park near my home. i like sitting by the wayle on fine afternoons. it was warm last sunday, so i went and sat on the river bank as usual. some children were playing games on the bank and there were some people rowing on the river. suddenly, one of the children kicked a ball very hard and it went towards a passing boat. some people on the bank called out to the man in the boat, but he did not hear them. the ball struck him so hard that he nearly fell into the water. i turned to look at the children, but there werent any in sight: they had all run away! the man laughed when he realized what had happened. he called out to the children and threw the ball back to the bank. lesson31 success story 成功者的故事yesterday afternoon frank hawkins was telling me about his experiences as a young man. frank is now the head of a very large business company, but as a boy he used to work in a small shop. it was his job to repair bicycles and at that time he used to work fourteen hours a day. he saved money for years and in 1938 he bought a small work-shop of his own. during the war frank used to make spare parts for aeroplanes. at that time he had two helpers. by the end of the war, the small work-shop had become a large factory which employed seven hundred and twenty-eight people. frank smiled when he remembered his hard early years and the long road to success. he was still smiling when the door opened and his wife came in. she wanted him to repair their sons bicycle! lesson32 shopping made easy 购物变得很方便people are not so honest as they once were. the temptation to steal is greater than ever before-especially in large shops. a detective recently watched a well-dressed woman who always went into a large store on monday mornings. one monday, there were fewer people in the shop than usual when the woman came in, so it was easier for the detective to watch her. the woman first bought a few small articles. after a little time, she chose one of the most expensive dresses in the shop and handed it to an assistant who wrapped it up for her as quickly as possible. then the woman simply took the parcel and walked out of the shop without paying. when she was arrested, the detective found out that the shop-assistant was her daughter. the girl gave her mother a free dress once a week !lesson33 out of the darkness 冲出黑暗nearly a week passed before the girl was able to explain what had happened to her. one afternoon she set out from the coast in a small boat and was caught in a storm. towards evening, the boat struck a rock and the girl jumped into the sea. then she swam to the shore after spending the whole night in the water. during that time she covered a distance of eight miles. early next morning, she saw a light ahead. she knew she was near the shore because the light was high up on the cliffs. on arriving at the shore, the girl struggled up the cliff towards the light she had seen. that was all she remembered. when she woke up a day later, she found herself生猪养殖基地建设项目可行性研究报告目
